Idle temperature high

Hi,

My FW13 shows the following at idle,

# framework_tool --thermal
  F75303_Local: 53 C
  F75303_CPU:   59 C
  F75303_DDR:   48 C
  APU:          60 C
  Fan Speed:  2457 RPM

Do i need to replace the thermal paste on the cpu?

Thanks

depend on conditions, and load. what is the power draw of the cpu/gpu/apu? are the fan vents clear of any obstructions?

This is what i have,

  Fan Speed:  2302 RPM

The laptop lid is closed as i use a thunderbolt dock primarily. The laptop is on a wooden table.

Try the linux tool:
amdgpu_top.

It will show you how many watts the cpu is using. If it is around 7-10W, it is idling.
If it is larger, there is something causing it. You would need to track it down.
It could be a process running. Use “top” to find the one using the most cpu.
Alternatively, it could be some misbehaving device triggering a lot of interrupts.

If you see 7-10W, and the cpu is still getting hot, then it might be a thermal paste problem.
If you open the lid, does it cool down at all?

This is what i see.

I see GPU power in W but not the CPU power.

It looks to me that it might be caused by firefox running. It is using about 30-40% of CPU.
If you close firefox, does the temp drop ?
How much CPU firefox uses will depend on which web pages or web sites you have open.
That GPU power is mislabeled really.
A more accurate title would be “APU Power”. I.e. combined CPU + iGPU power.
I don’t think it includes the dGPU power.

Being as the laptop lid is closed that is also adding some to the heat. It’s primary design is to be open while in use.

All modern devices run especially hot to eek out the best performance. Wooden desk should not matter much though it does act as an insulator underneath the device to some extent vs. a metal table.

Like what @James3 said there are processes in the background that are likely eating up CPU and GPU time that probably do not need to be active.

Almost all the chromium browsers all default to leaving themselves running in the background even when the application is quit which basically translates to a process that is going to eat up CPU time albeit at the lowest system priority ideally. Having to go and find that setting on each new installation saves a bit of memory and resource hogging unless the user prefers that sort of thing.

I ran my CPU at 15W for 10 minute and I got

--sensor name -------- temperature -------- ratio (fan_off and fan_max) --
local_f75303@4d       319 K (= 46 C)          20% (313 K and 343 K)
cpu_f75303@4d         316 K (= 43 C)           0% (319 K and 327 K)
ddr_f75303@4d         314 K (= 41 C)        N/A (fan_off=401 K, fan_max=401 K)
cpu@4c                332 K (= 59 C)           0% (376 K and 378 K)
Fan 0 RPM: 3181

Same APU temperature but lower first and second sensor temperature and higher fan RPM.
Possible reasons: Different fan curve, worse passive heat dissipation when lid closed.
To find out whether you need to replace the thermal paste run CPU stress testing at max power (30W) with lid open and check the APU temperature, if it’s 100C repaste it.
